01. Braking

Memory Item Loss of Braking

Nota más importante del Loss of Braking

When the flight crew sets the A/SKID & N/W STRG sw to OFF, the control of the braking system is transferred from the BSCU to the ABCU, and the alternate braking mode is activated. Consequently the PF should release the brake pedals before the PM selects the A/SKID off. This action avoids brutal braking application.

Cuales son los Braking Modes?

Cuántas aplicaciones de los frenos puede soportar el acumulador?

The accumulator can supply at least 7 full brake applications

Como funciona el Normal Braking?

Como funciona el Alternate Braking with Anti skid?

Como funciona el Alternate Braking without anti skid?

Como funciona el frenado con Parking Brake?

Qué es BSCU?

Brake and Steering Control Unit

Qué es la ABCU?

Alternate Braking Control Unit

A qué velocidad funciona el Anti skid?

The antiskid system is deactivated below 20 kt (ground speed)

Cual es la velocidad minima para la activación del Autobrake?

Therefore, if the aircraft makes an acceleration stop and begins to decelerate when the wheel speed is under 72 kt, the automatic braking will not activate because the ground spoilers will not extend.

Cual es la desaceleración segun el modo el Autobrake?

AUTO/BRK panel

The springloaded MAX, MED, and LO pushbutton switches arm the appropriate deceleration rate. The usage for each mode are as follow:

• MAX mode is normally selected for takeoff.

  In the case of an aborted takeoff, maximum pressure goes to the brakes, as soon as the system generates the ground spoiler deployment order

• MED or LO mode is normally selected for landing:

  • MED mode sends progressive pressure to the brakes 2 s after the ground spoilers deploy in order to decelerate the aircraft at 3 m/s² (9.8 ft/s²)

  • LO mode sends progressive pressure to the brakes 2 s after the ground spoilers deploy, in order to decelerate the aircraft at 2 m/s² (6.6 ft/s²).

Cuando se activa el DECEL Light del auto brake?

DECEL light

comes on green when the actual deceleration is 80 % of the selected rate Note: On slippery runways, the predetermined deceleration may not be reached, due to antiskid operation. In this case, the DECEL light will not come on. This does not mean that autobrake is not working.

Cuando aparece in arco verde y un arco ambar con respecto a la temperatura de los frenos?

Brake temperature

• Temperature normally appears in green.

• Green arc appears on the hottest wheel when one brake temperature exceeds 100 °C.

• Green arc becomes amber, and an ECAM caution appears, when the corresponding brake temperature exceeds 300 °C.
